Configuration File

Rather than give command-line options, many of the D2DX options can be given in a config file instead.

The release zip contains an example config file (d2dx_defaults.cfg). To use it, copy it to the game folder and rename it to "d2dx.cfg".

The example config file itself contains general documentation of the available options:

#
# This is an example config file for D2DX. 
#
# If you don't like the default settings, you can edit this file, rename it to "d2dx.cfg"
# and place it in the game folder.
#
